balls have contact. Also an inner race member 12 is provided which iscylindrical for contact with the rollers and has an outwardly extendingflange-like annular end thrust bearing plate 13 on one end thereof whichis parallel to the plate 10 and has a race groove or channel 11 in itsinner face, the balls being guided in the grooves or channels 11 and 11'and running clear of the members 9 and 12. The internal diameter of theannular plate 10 is greater than the external diameter of the racemember 12, affording clearance space to receive the continuous portionof the ring 4, and the external diameter of the plate 13 isv less thanthe internal diameter of the member 9 affording clearance spacereceiving the continuous portion of the ring 1, so that the cage mayturn without frictional contact with the housing parts.

The race member 9 may be secured in a wheel hub or may be stationarilysecured in such place as may be desired. And correspondingly the racemember 12 may be suitably secured to an axle or to a rotary shaft as maybe required.

In practical use the rollers are in bearing contact with the racemembers 9 and 12 and slightly clear the plates 10 and 13, so that theload is rotatively supported by rolling contact with negligiblefrictional resistance in the retaining rings. End thrust or load isborne by the balls and the thrust bearing plates 10 and 13 without anyserious frictional resistance.

What is claimed is:

1.' In an anti-friction journal bearing, a retaining cage including anouter spacing ring and a diametrically smaller inner spacing ring torotate in unison, each ring having roller-retaining slots in one edgeportion thereof and the rings arranged reversely each relatively to theother, to radially position cylindrical bearing rollers and enabletherings to co-operate to retain all the rollers on one and the sameplane of rotation.

2. In an anti-friction journal bearing, the combination of an outer cagering and an inner cage ring concentrically arranged to rotate in unisonand having each a plurality of roller-retaining slots intersecting oneedge thereof, each ring having also intermediate ball-retaining openingsadjacent to said edge, said edges being on opposite sides respectivelyof the plane of rotation of the ballretaining openings, cylindricalbearing rollers retained in said slots, and spherical hearing ballsretained in said openings.

3. In an anti-friction journal bearing, the combination of a pair ofconcentric race rings having each an annular side plate integraltherewith, each plate having a circular groove in its inner face, theplates being oppositely arranged, a cage comprising elastic continuouscyliznlrical outer and inner rings having each a plurality of slots andalso a plurality of circular openings alternately arranged, cylindricalbearing rollers retained in the slots between the race rings, and ballsdiametrically smaller than the rollers retained in the circular openingsbetween the side plates to operate in said grooves.

4. In an anti-friction journal bearing, a

cage comprising an elastic outer ring and an
